Orbit and dynamics
The path is an ellipse reaching 0.388 AU from the Sun at perihelion and 1.022 AU at aphelion, a radial span of 0.634 AU.
Applying Kepler's third law to a = 0.705 AU gives an orbital period of 0.59 yr, or about 216 days.
The high eccentricity (0.45) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 12.15° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 57.6 km/s at perihelion and falls to 21.9 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for 2016 MW4, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 24 observations and has a weighted RMS residual of 0.56 arcseconds.
Condition code U = 9 signals a poorly constrained orbit, so its future path should be treated as provisional.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
